![]() However, a super capacitor won't continue to operate for long without a permanent power supply. Super capacitors are a safer alternative as they don't pose the same risks that batteries do when they start to degrade or overheat, for example. This has a small amount of power that gives the dash cam enough time to save the video and shut down if it's disconnected from the power supply. These days, most new dash cams use an internal capacitor (or super capacitor) instead of an internal battery. Some models can also be hardwired to the car's power supply. You'll need a cable (which comes with most models) to run the camera from the car's 12V socket. This lets the camera run without a permanent power connection, though duration varies between manufacturers. This also applies to speed and impact location stamping, if available. Stamping GPS data on the video can be useful in the event of a crash, as police and insurance agencies don't need to install third-party software to access it. Some models come with software to view the recorded data, while others will stamp this information on the video.
